Groundwater in Morris County contains radon, uranium, arsenic, chloride, iron, lead, manganese, PFOA, PFOS, and sulfate. Multiple contaminants in this county exceed EPA health standards, making testing and treatment important for well owners.
The crystalline rock beneath Morris County naturally releases radon, uranium, manganese, and iron into groundwater as water passes through fractures and mineral layers over time. Road salt applied to county roads contributes chloride and sulfate to shallow groundwater. PFOA and PFOS are industrial chemicals that have entered the water supply through contamination from manufacturing sites and other sources.
Groundwater in this county is moderately hard, driven by moderate sodium levels and a balanced mineral composition from the crystalline rock. The bedrock dissolves minerals slowly into the water as it flows through, creating this moderate character. These mineral traits show up in wells across the county but vary from well to well depending on depth and location.
Wells in Morris County commonly have radon, uranium, arsenic, lead, and the industrial chemicals PFOA and PFOS at levels above EPA health standards. Radon is a radioactive gas that increases lung cancer risk over time. Uranium can harm your kidneys and bones. Arsenic raises cancer risk with long-term exposure. Lead damages children's brains and nervous systems at any level. PFOA and PFOS are persistent chemicals that build up in your body and can affect your immune system and liver.
County wells are moderately hard with moderate sodium content. You may notice white scale buildup on faucets and showerheads, or staining on dishes and laundry. Hard water can shorten the lifespan of water heaters and dishwashers. Some people detect a slightly salty or metallic taste.
Every well in Morris County is different--yours could have much higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. We recommend a comprehensive metals and chemicals panel, which typically costs $200 to $400. Treatment options include reverse osmosis systems, activated carbon filters, and radon mitigation depending on what testing reveals.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
